Canadian Boating Practice Exam

Boats over 12m and up to 24m are required to have a self-igniting light attached to any lifebuoy. The other options, a lifting harness with rigging, two SOLAS-type lifebuoys, and a buoyant heaving line at least 15m in length, are all incorrect because they are not specifically mentioned as required equipment for boats within this size range. While these items may be useful to have on a boat, they are not explicitly mandated by regulations for boats of this size. Therefore, the correct answer is A.
